In disclosed embodiments, compression circuitry may compress data blocks and compressed write data blocks and corresponding compression metadata to a certain level in a cache/memory hierarchy. In some embodiments, the compression circuitry is configured to detect a pre-determined set of data values in a block of data to be compressed. In response, the compression circuitry may write a special metadata value for the data block to data storage circuitry to indicate compression of the data block, without writing a compressed version of the data block to the data storage circuitry. This may advantageously improve performance and reduce power consumption for data blocks with certain data values (e.g., having uniform pixel/texel values).
An apparatus, comprising:
A method comprising:
A non-transitory computer readable storage medium having stored thereon design information that specifies a design of at least a portion of a hardware integrated circuit in a format recognized by a semiconductor fabrication system that is configured to use the design information to produce the circuit according to the design, including:
